It probably isn't; she's probably using less than 100W for her compute on average. If she's using a laptop it definitely isn't.

This stretch of road is mostly a rural 2 lane highway; you don't have an easy way to pass a semi anyway. They are rare but regular trucks are not. Drafting any car should give some benefit, and aero benefits usually start to become noticeable when you get within 5 seconds of the previous...

Music might take 30 Watts... per hour. Is essentially a non-factor. If you run out of battery 1 mile before your destination you can blame me.

This is really odd. You are correct that your displayed range changes based on available kWh which drops as power is used. However, this power usage is not counted in your Wh/mile odometer display.

I wouldn't hesitate to do the Farmington-Page leg in a model 3 LR with 82kw battery. I would start at 100% with a preconditioned battery, start early to minimize the need for AC and keep an eye on the trip energy projection. You could avoid any risk by staying overnight in Bluff or Monument...

Unfortunately, that efficiency is likely accurate, in which case you are spending an extra 15% on electricity vs. the optimum. When charging, not all power is used for charging; some constant overhead is used to operate the computer and BMS; let's say 200W. At 120V, this would be about 1.5A...

There is a really good thread in the Model 3 subforum. In summary the Hubbell 9450a and Bryand 9450fr are great, Cooper 5754n is good, do not use the Leviton 279-S00.

Here are the results of a recent Tesla model 3 charging test. Conveniently some of their results are really easy to remember. From the first infographic: 0-60% in 21 minutes 60-90% in 21 minutes 90-100% in 21 minutes Also from the article: For now, the difference between V2 and V3...

It would be, but it's not. The mile estimate that replaces battery percentage takes the remaining battery kWh and multiplies it by the EPA rated miles/kWh.

It took 36 minutes at the charger, it's in the OP.

The advantage to using battery % instead of miles is it reduces anxiety when dealing with "battery degradation"/reduced range that will happen. Some of the degradation is real, usually a good amount of the displayed degradation is because the BMS's guess at remaining charge has drifted a...

Thanks for the input, that's the better approach :)

Your 14-30 should be able to recharge your battery from dead to 100% in 14h, or add 70% in about 10h.

If I plug in 233V*31A*95.6% efficiency, I get 6.9kW. 6.9kW/.27kWh/mi = 25.5 miles/hour. I messed up something else - the 270Wh/mile EPA number actually already includes a charge efficiency of ~88%. I should have used 238Wh/mile for full equivalence - although I know they aren't the most useful...

That makes sense, thanks for the clarification! "It took 87.868 kWh to add 77.702 kWh to the battery of the Long Range" - 77.702 / 87.868 = 88.4% charging efficiency... what charging equipment were they using? Most 240v sources seem to charge at >= 90% efficiency, 88.4% seems like a 120V...

The EPA test for the 2021 MY in September last year gave it a 330.178 mile range using 77.7kWh. As to why the Performance have been at 81.5kWh and the LR have been at 78.9kWh, my bet is that it's an identical pack just with different charge limits set. It should give the P a little extra oomph...

I think the energy buffer SMT is reporting is at the bottom: 3.5kWh bottom buffer, so when you're charged to 79kWh you have 75.5kWh actual. With a max capacity limited to 79kWh there's also a ~3kWh buffer at the top. That means that 0-100% in the car corresponds to 4-96% of the full 82kWh...

Thanks for your input @jcanoe, I really appreciate your finding an issue and providing solid data points: 120V/16A: ~6miles 240V/16A: 12.x miles 240V/32A: 25.5 miles I'm a little surprised - your 120V data matches what I had found but not your 240V data. I get your 240V values if I set...

Tesla's official charging rates are estimates, but I think they make NEMA 5-15 charging seem really bad (3 miles/hour for a model 3?). I've plugged some data into a spreadsheet to calculate charging times for various volts and amps. volts amps (continuous) kW efficiency kW actual hours to...

I was thinking that the car heats the battery pack to operating temp and cools the cabin, then would turn both off after a drive, letting temps drift towards ambient. However, if the car actively chills the battery for "storage mode" after driving then I guess energy consumption could be higher.

See the other post here. I don't understand how this is remotely possible given thermodynamics...

I'm not sure why your consumption is so high, but I can say your math doesn't add up. Considering a worst case 65kwh pack/.330kwh per mile = 195 miles, 20% of that is 39 miles.

The data comes from "SMT - Scan My Tesla. You need 2 adapters to make it work.

I feel like a doofus. kWh, not kw...

That makes sense. I'm looking into the battery capacity a bit more: BeardedTeslaGuy's new battery is reading 79.2kw, a little low compared to 80.5 - but higher than the previous battery's 77.8kw "when new". If those numbers are correct, he should actually get the EPA rated range of the older...

We already knew that Model Y Performance had 82kw packs... but this is a LR. He doesn't mention it explicitly, but he shows a sticker with 19" rims, so it is definitely a LR. Produced May 21st. I wouldn't be surprised if it's a partial/phased rollout - some current deliveries still have the...

It's funny. Part of me would jump to spend 10k to get 300 miles at 75mph from a MY instead of 220 miles. A bigger capacity battery would also have the benefit of keeping V3 SC rates higher for longer, and allow for better range with bikes on the hitch. However the reason I personally want that...

My wife and I have been car free for years but are moving to a more remote location and are looking at cars. At this point we're heavily considering EVs, despite planning on living in a charging desert. We did an extended test drive in a model Y a month ago. The trickiest leg we'll probably...
